Answer:

x = 28/3

Step-by-step explanation:

We can solve this problem by using similar triangles:

Both of these triangles have a 90 degree angle and they share angle A, meaning that they are similar by AA similarity.

Now we can set up ratios and solve:

13/7 = (x+8)/x

multiply both sides by x:

13x/7 = x+8

Multiply both sides by 7:

13x = 7x + 56

move the 7x over and divide by 6:

6x = 56

x = 28/3

Answer:

9 1/3 or 9.3333333333

Step-by-step explanation:

Triangle ABC is similar to Triangle ADE because they are proportional.  It is a 7:13 ratio as shown by segments CB and ED.

Therefore, the ratio from AB to AD would also have to be 7:13.  The ratio as shown by the picture is x:x+8.  Therefore x:x+8=7:13.

Now you put this in fraction form.  \frac{x}{x+8}=\frac{7}{13} You multiply both sides by X+8 and get X=\frac{7x+56}{13}.  Now you multiply both sides by 13 and get 13X=7x+56.  Now you have cleared the fractions so it looks neater.  Next, you subtract both sides by 7x and get 6x=56.  Finally you divide both sides by 6 and get x=9 1/3

Answer:

The answer is A. (x-6)(x-6)

Step-by-step explanation:

x^2 -12x + 36

x^2 - (6+6) x+36

x^2 - 6x - 6x + 36

x( x - 6) -6(x-6)

(x-6)(x-6)

How to determine if an expression is rational or irrational?
Neporo4naja [7]
If it is rational, it has a terminating decimal or a repeated decimal number (ex. 56, or 1.25, or 3.666...)

If it is irrational, it is an ongoing number with no pattern (ex. 3.14159265... Which is pi)

A factory sells backpacks for $35 each. The cost to make 1 backpack is $15. In addition to the cost of making backpacks, the fac
Otrada [13]

Answer:9400 backpacks

\geqStep-by-step explanation

since the number of packs to be sold in a  is represented by x,

selling price for 1 week = 35x

cost price for 1 week = 15x

profit = 35x-15x = 20x

additional cost of production = 11,000

this implies that 20x - 11,000 \geq 7800

20x - 11,000 \geq 7,800

20x \geq 7800+ 11000

20x \geq 18,800

x \geq 18800/2

x \geq 9,400

at least 9,400 packs have to be sold each week to make a profit of $7800
